I'm wondering where Bangaloreans or Indians in general would look for components and equipment... do you all buy stuff on-line, or are there hobbyist/professional electronics suppliers in town?

Well some stuff can be bought online(boards, sensors, etc) for others it makes sense to visit the local electronics market over farnell / digikey (you would be surprised at deals you can get! but beware - you can get conned easily if you do not know the subject or are looking for specifics) Availability is limited to components / items that are time tested and are used for production - The hobbyist scene is quiet catching up in India... we(Simple Labs - http://build.simplelabs.co.in/) are seeing an increase in product requests however there is a long way to go... it would be difficult to find all the stuff as in digikey or other sites...let me know if you need any help
